In the interests of keeping code clean, the simplest possible conditional syntax should be used. That means
|
|
|
|
* using the ``++??=++`` operator for a self-assign-if-not-null operation,
|
|
* using the ``++??++`` operator for an assign-if-not-null operation, and
|
|
* using the ternary operator ``++?:++`` for assignment to a single variable.

== Noncompliant Code Example
|
|
|
|
----
|
|
object a = null, b = null, x;
|
|
|
|
if (a != null) // Noncompliant; needlessly verbose
|
|
{
|
|
x = a;
|
|
}
|
|
else
|
|
{
|
|
x = b;
|
|
}
|
|
|
|
x = a != null ? a : b; // Noncompliant; better but could still be simplified
|
|
|
|
x = (a == null) ? new object() : a; // Noncompliant
|
|
|
|
if (condition) // Noncompliant
|
|
{
|
|
x = a;
|
|
}
|
|
else
|
|
{
|
|
x = b;
|
|
}
|
|
|
|
if (a == null) // Noncompliant
|
|
a = new object();
|
|
|
|
var y = null ?? new object(); // Noncompliant
|
|
|
|
a = a ?? new object(); // Noncompliant for C# 8

== Compliant Solution
|
|
|
|
----
|
|
object x;
|
|
|
|
x = a ?? b;
|
|
x = a ?? b;
|
|
x = a ?? new object();
|
|
x = condition ? a : b;
|
|
a ??= new object();
|
|
var y = new object();
|
|
a ??= new object();
